So I just started vaping again about 3 weeks ago, when I started I bought from my local smoke shop a generic ecig with a no name cart and no name 650mah battery. I really enjoyed it so I decided to step up my vaping equipment, so I purchased the highly reviewed kanger aerotank with a VV 1200mah battery, any reason why this no name disposable ecig is giving me twice as good vapor production and a smoother, more flavorful hit than my aerotank, I have tried every voltage and airflow combination and maybe 1ml out of my 2.5 I can vape on it like I want to other then that I'm getting burnt tastes and lack of vapor production in it and constantly have to adjust the voltage because it seems every time I hit my aero tank it hits differently with the same airflow and voltage. Is there something I'm doing wrong? Is it my battery possibly? I love vaping but looking for some experienced help before I go and buy a vamo in hopes of a better vape, was also considering the aspire nautilus, just not sure which route to go. Oh and btw I've been smoking 20pg 80vg eliquid at 12 and 18mg trying to find which is best, I am definitely sensitive to pg because 50/50 60/40 and 100pg makes my throat super sore. Sorry for the long rant but just looking for some experienced guidance here....
